Hi Ian, Glad the QFS business seems solved. Thanks for that bug report.
Regarding the initial guesses this is what I experience (I've managed to understand the symptoms a bit more specifically now): I set up the initial guess values in the GDS window and run the fit. When I've finished working I save the project and exit. When I reload the project the initial guesses for guess parameters with an initial guess of 0 are set to the final guess from the previous fit (see attached screenshot of GDS + history window to demonstrate(artemis gds init guess 0 bug.png)).
Again, good eye. I was using the value of the initial guess as a logical flag to choose between the initial value and the best fit value as the value to display. An initial guess of 0, of course, evaluates false, thus it would display the best fit. That's just a silly programmer error and will be fixed in the next trial release.
Regarding the issue I mentioned at the start about reopening project files I made in 0.9.21 I've attached the following (project + logs from 0.9.21 and from similar issues I've experienced (very) intermittently in 0.9.20):
Project file saved in 0.9.21 that I can't reopen - artemis testing.fpj Log file from trying to open it (0.9.21) - dartemis.log
Project file saved in 0.9.20 that I can't reopen - dualedgefitting.fpj Log file from trying to open it (0.9.20) - dartemis_current.log
I will look into this, but not today. I was in a meeting since 9 am... :( B -- Bruce Ravel ------------------------------------ bravel@bnl.gov National Institute of Standards and Technology Synchrotron Science Group at NSLS-II Building 535A Upton NY, 11973 Homepage: http://bruceravel.github.io/home/ Software: https://github.com/bruceravel Demeter: http://bruceravel.github.io/demeter/
